Inovonics 514 - INOmini FM Multiplex Decoder

Overview

Inovonics’ INOmini 514 is a standalone decoder for FM-stereo multiplex signals.  It accepts a demodulated FM-baseband input and decodes the signal to discrete left and right channel audio.  The recovered stereo program is available as a professional line-level balanced output, and also as an AES digital audio signal. 

Local alarm ‘tallies’ and selectable de-emphasis curves make the INOmini 514 an essential tool for professional applications wherever a stereo-baseband signal needs to be decoded and monitored.

Features

  • Decodes Composite/MPX signal into L/R audio
  • Analog L/R and AES-digital program line outputs
  • Accurate front-panel metering
  • Front-panel alarms with rear-panel ‘tallies’ for program Audio Loss (silence sense) and stereo Pilot Loss (stereo/mono status)
  • Conforms to the worldwide FM ‘pilot-tone’ system; selectable 75μs/50μs de-emphasis

 

Specifications

MULTIPLEX (MPX) INPUT
Unbalanced/bridging (BNC); 10k input impedance; requires 0.5V p-p minimum signal. 

L/R ANALOG LINE OUTPUTS
Active-balanced (XLR), 200-ohm source impedance; +4dBu output at ‘0dB’ on front-panel meter. 

AES DIGITAL OUTPUT
Transformer-balanced (XLR), 44.1kHz sampling rate; –6dBFS output at ‘0dB’ on front-panel meter.

HEADPHONE JACK
3.5mm (TRS) for low-Z or high-Z phones; fixed listening level. 

PROGRAM AUDIO DE-EMPHASIS:
75μs/50μs, selected with push-on jumpers under the top cover.

FORCED-MONO OPERATION
Enabled with a push-on jumper under the top cover. 

AUDIO FREQUENCY RESPONSE
Follows selected de-emphasis characteristic ±0.5dB, 20Hz to 15kHz.

NOISE
(Unweighted SNR re: ±75kHz deviation):
MONO: ≥72dB; analog/digital 
STEREO: ≥70dB; analog/digital

DISTORTION
≤0.05% THD, 20Hz to 15kHz (analog/digital)

STEREO SEPARATION
>50dB 20Hz to 15kHz (analog/digital)

ALARM TALLIES
Individual open-collector NPN transistor outputs for Program Audio Loss (either/both channels) and Pilot Loss (stereo/mono indicator)

POWER REQUIREMENT
12VDC at 230mA. A ‘wall-outlet transformer’ (WallWart®) switching-type power supply appropriate to the destination AC mains voltage is provided. 

MOUNTING OPTIONS 
An optional rack adapter accepts up to three INOmini modules in a 1U, 19-inch rack space. Alternatively the 514 may easily be fastened to any convenient surface with two small screws.
